Signs of Popeye Disease in Aquarium Fish

What is Bilateral Popeye?

Bilateral Popeye is a case in which both eyes of a fish are swollen and infected. This can be due to internal infection or improper outside water conditions, which infect the fins and surrounding parts of the eye and cause it to swell.

Common Causes of Fish Popeye

The most common cause of Popeye fish is exophthalmia. Exophthalmia is a technique in which swelling behind the eye tries to push the eye from inside, resulting in a Popeye. 

The second most common cause of Popeye’s disease is trauma. In trauma, fish are damaged by the aquarium’s environment, which causes swelling in the eyes. If any of your fish is diagnosed with Popeye disease, check your water first.

Poor water conditions, improper supersaturation of gas in the water, and chemical changes in water cause infection in the whole aquarium. If you observe any bubbles in the water or on the skin of your fish, you must be careful as it may be a sign of Popeye disease.

The third common cause of Popeye fish can be diagnosed through fish kidneys or gills. If your fish kidneys are not functioning properly, they might start taking on excess water, which sticks out on the body and tissues behind the fish’s eyes. You must check up on your fish’s kidneys and make it functional before Popeye becomes threatening.

Another cause of Popeye is infection, which builds up from different virus-spreading organisms such as bacteria, fungi, or parasites.

The exact symptoms of this disease are not very obvious.

SUMMARY

Popeye is usually the result of a poor aquarium environment, exophthalmia, dust, infection, injury, or dirt particles. Disease may occur due to parasites, fungi, or bacteria. Check the quality of water first if any fish is diagnosed with Popeye.

Popeye treatment is not easy if you haven’t identified the cause of this disease, and it becomes even more difficult when the cornea of fish is damaged. After the diagnosis, You will be required to maintain proper water conditions in the aquarium to save other fish. If the Popeye has been caused by any trauma, you will have to allow your fish to develop a secondary skin layer on its own, which may take some time.

In this case, you will also have to remove any decorations, such as sharp rocks and tiny plants, from the pool to avoid any further trauma. Sea salt also helps to heal the body where there is a trauma.

If you diagnose Popeye in any of your fish, keep it alone to avoid the spread of the virus and the danger of infection to other fish in the aquarium. Arrange optimal and medicated water conditions for the suffering fish to survive and get cured.

2. Check Water Conditions

The Popeye is mainly caused by improper water conditions. So, check your aquarium water and observe ammonia and nitrate levels in the water. Suppose these chemicals are not found in a proper proportionate. Do not change the water conditions like lighting and temperature. You must check the pH level of the water and maintain it to its standard level to provide a healthy environment for the fish.

3. Using Epsom Salt

Epsom is a mixture composed of oxygen, sulfur, and magnesium. For a long time, Epsom salt has been used as a cure for aquatic species. This salt is the best and timely cure for minor pains, aches, and other diseases. In the case of Popeye, it is used to reduce swelling, giving temporary relief to fish.

Using Epsom Salt in the case of Popeye

Add 2-3 teaspoons of Epsom salt in five gallons of water tank. This will act slowly, but within a few days, you will observe a reduction in swelling in the eye. Do not forget to observe your fish daily and observe the changes. This will also help you to maintain proper Epsom salt in the water.

4. Antibiotics for Bacterial Infections

If your fish has been diagnosed with a bacterial infection such as a kidney or gills infection, you will address antibiotics for the cure of this disease. You can use any aquatic antibiotics, such as broad-spectrum antibiotics and Baytril, for the treatment. Baytril is usually used for goldfish, and it has shown some exceptional results, but it can also be used for other fish.

These antibiotics are usually taken with food but can also be used as an outer gel to be applied to the skin of the fish. 

The whole treatment can take many weeks, depending on the severity of the disease. But you should keep checking the infected fish. I recommend you check the water quality where it was infected and medicate it immediately to prevent other fish in the aquarium from getting the same disease.
